Um.. .its a dummy light. It comes on whenever the hell it wants, just like in the middle of dyno pulls.

Run on the dyno - light should come on.
Do a burn out - Light should not come on.

Both are front tires sitting still and rear moving.

 

All it will do is flash the light, that is all.. Shut the car off and go for a drive, the light will not come back on..

I'm very curious.. How EXACTLY will an ABS light slow the rear wheels..? For the reason it would come on during a dyno pull, is what lilspic said.. The rear tires are moving and the front arent.. In no way, shape or form is that cause to "activate" or drag the rear brakes.. The only thing it means is that a wheel speed sensor (the front) are reading 0MPH, as the rear are reading ***MPH, meaning, you wont have ABS when you hit the brakes next time..

Do you work for them..? I really hope not..

 

Wow.. Just wow...

I'm not sure on GM's ABS system's, but on Ford's ABS system, after 13 MPH, if 1 wheel speed sensor is reading more then 2 mph off the other 3, while moving, not braking, the ABS light will come on..

You guys are really hurting yuorself trying to argue this point..

 

difference being one the brakes are applied or the car is rolling...the other the fronts don't move and the brake pedal isn't pressed
not to make the big mention but all manufcaturers have difference programs for there TC and ABS systems

 

i didnt hurt myself for shit, i was asking a question. i didnt argue the ABS point.

 

True, however, NONE of them will activate the rear brakes or do anything of the likes, for the ABS.. Traction control, yes, ABS, no..

I'm rather confused in this statement you just made..

 

are you saying that just if the ABS light comes on?..if so that's true...but with new fly by wire it is becoming standard for ice conditions that the throttle start closing...apparently the GTO doesn't have this

 

OK.. I'm going to try and sum this up from an outsiders few, sems I have no experience on an AWD dyno..




Gathering the info from this statement, its seems to me that both rollers on the dyno are connected, unless dissconnected.. So, I'm going to assume that an "AWD" mode, the HP/Trq reading are taken by using some sort of table using the power sent to BOTH rollers.. Correct?

So, your dynoing a 2wd car, in "AWD" mode, which means both rollers are still connected, for the reasoning stated above.. Therefore, I'm guessing that the table using the measure the HP/Trq is still the SAME table use to measure 2wd cars, which means that the front tires are causing the front rollers to "drag", due to no power being at the front wheels.. So, using that same table to calculate AWD HP/Trq, the numbers are much lower on a 2wd car, because the table is equating both rollers, not just the powered rollers..

Correct? thats what I'm gathering from all this..

But doing that is, well, kinda stupid.. 2WD dyno's, the ABS light comes on as well, simply for tha fact the the WSS's are getting mixed readings.. Shut the car off and take it for a drive, no ABS light and it does NO damage to any of the sensor's or ABS system.. as litlespic said, its simply a dummy light..

 

What is the world coming to when the most intelligent sounding poster in a thread is ToOCoOl?

 

When the ABS light comes on, the only thing that means is that during an hard stop, say when the ABS would normally engage, you will have no ABS and possibly lock up the tires..

Traction control works a little differnt, but almost every vehicle with traction control, you can turn off, so.. Yea..
